Operating Time Accumulate Method in Reliability Test of a Towed Antiaircraft Gun System

In order to solve the problem of operating time accumulation in reliability test of a towed antiaircraft gun under different work modes, a operating time accumulate method was proposed. Through converting system work time to subsystem working time, statisticing the various subsystem work time under different work modes by weighted method, transformed jointly work time to subsystem independent work time, the operating time accumulate method was given with the example analysis. The test results show that the method can be used to evaluate the reliability of weapon system.
